Adapting Query Expansion to Search Proficiency
Publication

Presented at the
Information Retrieval over Query Sessions, Barcelona
We argue that query expansion (QE) based on the full ses-
sion improves the overall search experience provided that we know how
to adapt the QE weighting schema to a user's search proficiency. We
propose a strategy to predict search ability from session parameters. Us-
ing an exponential model and these metrics we set user dependent QE
coefficients. We evaluate this approach on TREC 2011 session track data.
